Benzene is commonly regarded as a resonance hybrid ofthe two Kekule structures. but other possible structures canalso contribute. Draw three other structures in which thereare only covalent n bonds (al lowing for bonding betweensome non-adjacent C atoms) and two structures in whichthere is one ionic bond. Why may these structures be ignoredin simple descriptions of the molecule?
